Building Permits & Zoning in Maryland
Baltimore City and five surrounding counties with real parcel, authority, portal, and zoning-source coverage
Permit Requirements in Maryland
The Maryland Building Performance Standards adopt statewide minimum building, residential, energy, accessibility, and related construction codes. Baltimore City and each county administer permits locally and may adopt local amendments. Maryland is not a single statewide permit portal: the parcel's independent city, county, or incorporated municipality determines the filing path.
Permit Types
Common residential permit types organized by jurisdiction — building, zoning, trades, accessory structures, land use, and site approvals.
Local Authority
Coverage is limited to the Baltimore-area launch jurisdictions; incorporated-city exceptions are routed separately.
County Administration
Baltimore City is an independent city; Baltimore County is a separate permit authority. Surrounding county and municipal authority is resolved from the parcel.
